NCT03023475

Brief Summary

Endoscopic radial artery harvesting in coronary bypass surgery is routinely performed by the investigators. In this study, the investigators want to compare the MiFusion TLS2 (Endotrust GmbH, Germany) device to the LigaSure Maryland Jaw (Medtronic, USA). The vessel harvesting is performed in the standard fashion according to the institutional routine. The patients are randomized preoperatively to one of the devices. The proximal end of the radial artery will be preserved and deep-frozen for histological assessment. Endothelial integrity will be investigated using Hematoxylin-Eosin, CD31 and endothelial nitrogen monoxide synthase.

Conditions

Outcome Measures

Primary Outcomes (1)

  • Endothelial integrity of the radial artery using histological examination.

    Through study completion, an average of 1 year.

Secondary Outcomes (3)

  • Harvesting time

    The harvesting time will be measured during the vessel harvesting surgery.

  • Hemostasis in the arm indicated by bleeding from radial artery side branches or veins in the arm.

    Intraoperatively and directly after vessel harvesting the arm is controlled using the endoscope and bleeding can be detected during this control. End of surgery is end of this outcome parameter.

  • Accuracy of vessel sealing, if side branches of the radial artery are bleeding after blood insufflation, additional clips have to placed at the side branch.

    The blood insufflation is performed immediately after vessel harvesting and leaks can be detected.

Study Arms (2)

LigaSure endoscopic radial harvesting

ACTIVE COMPARATOR
